Ramp map
A node of the Style graph, in the Colour group.
An artist's ramp read from a picture strip: the number 0 to 1 picks along it, dark to light. A strip of several rows gives each ramp its own row. With no picture, the colour's own bands. Wire Key light through Remap into it.
Takes: light (scalar), ramp (ramp), file (text) · Gives: layer
Settings
| Setting | What it does | Range | Default |

| File | The picture strip's file; the node keeps its pixels. | text | — |
Every setting is also an input: wire a value into it to change it per pixel. On the command line: pxr graph set game.pixor --which style --node ramp-map --set KEY=VALUE.

What it wires to
Its light input takes a scalar, which these give: Add, Agreement, As a number, Blur, Cavity, Divide, Emissive, Fill light, Fraction, Hold between, Larger, Length, and 21 more.
What it gives, a layer, goes into: CRT, Output, Cleanup, Combine, Lines, Mesh edges, Choose by mask, Colour edges, Dither mix, Flatten, Layer over, Paint, and 10 more.
In the app, drag a wire from one of its dots: every dot the wire fits is ringed.
How it fits with the rest: the Style graph in the manual.
